Detailed Implementation

[0017] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0018] The following is for reference. Figures 1-2 An electronic control device 100 according to an embodiment of the present invention includes: The device body 10 has an installation space 11 for installing components; An electrical control cover plate 20 is provided on the main body 10 of the device. The electrical control cover plate 20 has a maintenance hole 21 that penetrates through the electrical control cover plate 20 along the thickness direction. The maintenance hole 21 is connected to the installation space 11. Mounting base 30, which is fitted and fixed to the electrical control cover 20, with at least a portion of the mounting base 30 located within the mounting space 11; A sealing cover 40 is fixed to the mounting base 30 to seal the maintenance hole 21.

[0019] The main body 10 of the device has an installation space 11 for installing components. The installation space 11 also contains high-voltage busbars and other components. The electrical control cover 20 is located on the main body 10 of the device to cover the installation space 11 and provide protection.

[0020] The electrical control cover 20 has a maintenance hole 21 that extends through the electrical control cover 20 along its thickness direction. The maintenance hole 21 is connected to the installation space 11 and is positioned corresponding to the high-voltage busbar. This allows for regular inspection and maintenance of the high-voltage busbar through the maintenance hole 21, thereby avoiding the need to remove the entire electrical control cover 20 during inspection and maintenance of the high-voltage busbar. This simplifies the operation process and shortens the downtime of the electrical control device 100.

[0021] The mounting base 30 is assembled with the electronic control cover 20 to be fixed to the electronic control cover 20. In some embodiments of the present invention, the mounting base 30 and the electronic control cover 20 can be fixedly connected by snap-fit ​​or by bolts. However, in the present invention, the mounting base 30 and the electronic control cover 20 can also be fixedly connected by other means, as long as the mounting base 30 and the electronic control cover 20 are assembled with each other to be fixed to the electronic control cover 20.

[0022] At least a portion of the mounting base 30 is located within the mounting space 11. In some embodiments of the present invention, the mounting base 30 may have one-half, one-third, or other proportions located within the mounting space 11. However, the present invention is not limited to this, and the mounting base 30 may also have other proportions located within the mounting space 11, as long as at least a portion of the mounting base 30 is located within the mounting space 11.

[0023] The sealing cover 40 is fixed to the mounting base 30 to seal the maintenance hole 21. The sealing cover 40 and the mounting base 30 can also be connected by threads or by snap-fit, but the invention is not limited to these methods. The sealing cover 40 and the mounting base 30 can also be fixedly connected in other ways, as long as the sealing cover 40 is fixed to the mounting base 30 to seal the maintenance hole 21. The sealing cover 40, fixed to the mounting base 30 to seal the maintenance hole 21, can prevent external moisture, dust, mud, insects, corrosive gases, etc., from entering the equipment, maintaining internal cleanliness. It also provides safety protection; the sealing cover 40 can prevent accidental contact and injury. In the event of a minor internal explosion or component detachment, the sealing cover 40 can also act as a barrier to prevent internal fragments from flying out and injuring people.

[0024] Mounting base 30 provides a mounting base for sealing cover 40 to be installed in maintenance hole 21, so that sealing cover 40 can be installed firmly and more easily on electrical control cover plate 20. This helps to reduce the use of bolts, thereby reducing the complexity of disassembling and assembling sealing cover 40. As a result, when inspecting and maintaining high voltage busbar, only sealing cover 40 needs to be removed, eliminating the need to disassemble and assemble the entire electrical control cover plate 20. This greatly improves the maintenance efficiency and convenience of high voltage busbar in electrical control device 100.

[0025] Furthermore, both the mounting base 30 and the sealing cover 40 can be injection molded parts. The injection molding process can easily realize complex structures that are difficult or impossible to process in sheet metal, such as snaps, barbs, reinforcing ribs, labyrinth sealing paths, etc., so that the injection molded sealing cover 40 can be designed for tool-free quick installation / removal (such as rotation clamping, press locking), while sheet metal covers usually require screws or special clamps for fixation, and disassembly and assembly are relatively time-consuming.

[0026] Furthermore, injection-molded parts have low density, short molding cycles, high automation, and low production costs, which helps reduce the weight and cost of the sealing cap 40. Injection-molded parts are natural electrical insulators, preventing accidental electric shock, and are suitable for electrical equipment, battery packs, etc. Sheet metal caps are conductors, which may cause short circuits or require additional insulation. Injection-molded parts allow for precise control of dimensional tolerances through the mold, ensuring a tighter fit between the sealing cap 40 and the maintenance hole 21, reducing the risk of leakage. Sheet metal may undergo permanent deformation (warping) after repeated disassembly and reassembly, leading to seal failure.

[0027] According to an embodiment of the present invention, the electrical control device 100 has a maintenance hole 21 formed in the electrical control cover plate 20, which extends through the electrical control cover plate 20 along its thickness direction. The maintenance hole 21 communicates with the installation space 11. The mounting base 30 is fitted and fixed to the electrical control cover plate 20. At least a portion of the mounting base 30 is located within the installation space 11. The sealing cover 40 is fixed to the mounting base 30 to seal the maintenance hole 21. The mounting base 30 enables a fixed connection between the sealing cover 40 and the electrical control cover plate 20, and also achieves the sealing of the maintenance hole 21. When inspecting and maintaining the high-voltage busbar, only the sealing cover 40 needs to be removed, eliminating the need to disassemble the entire electrical control cover plate 20. This greatly improves the maintenance efficiency and convenience of the high-voltage busbar within the electrical control device 100.

[0028] According to some embodiments of the present invention, such as Figure 2 As shown, the mounting base 30 and the sealing cover 40 are detachably connected. In some embodiments of the present invention, the mounting base 30 and the sealing cover 40 can be connected by threads or by snap-fit. However, the present invention is not limited to these. The mounting base 30 and the sealing cover 40 can also be detachably connected in other ways, as long as the mounting base 30 and the sealing cover 40 are detachably connected.

[0029] The mounting base 30 and the sealing cover 40 are detachably connected, which facilitates the installation and removal of the sealing cover 40, thereby facilitating the inspection and maintenance of the high-voltage busbar.

[0030] In a specific embodiment of the present invention, the mounting base 30 and the sealing cover 40 can be connected by threads, allowing maintenance to be completed with only one tool disassembly. A sealing ring 42 can be provided between the sealing cover 40 and the electrical control cover 20. When the mounting base 30 and the sealing cover 40 are assembled and rotated, the relative movement between the sealing cover 40 and the inspection port generates an axial clamping force, which can uniformly compress the sealing ring 42. By controlling the tightening torque or the number of turns, the sealing pressure can be precisely set to ensure consistent and reliable sealing performance, preventing leakage due to insufficient pressure or damage to the sealing ring 42 due to excessive pressure. During long-term use, the sealing ring 42 may undergo creep or permanent compression deformation, resulting in a decrease in clamping force. In this case, simply tightening the sealing cover 40 again will reapply pressure and restore the sealing performance without the need to replace parts.

[0031] Furthermore, compared to bolted connections, threads effectively prevent automatic loosening by relying on the friction and radial expansion between the threaded pairs. They are also inherently vibration-resistant, reducing the number of parts and the risk of loosening. The sealing cap 40 can be directly screwed into the access port. Its overall shape is cylindrical or conical, without radially protruding flanges or handles, which is highly advantageous for installations in confined spaces, densely packed pipes, or applications requiring low wind resistance. This greatly improves the positional flexibility of the electrical control device 100 and reduces the difficulty of maintenance.

[0032] Normally, tightening or loosening can be achieved with just an adjustable wrench, pipe wrench, or special wrench, without the need to disassemble or assemble multiple bolts or operate clamps. The threaded structure experiences minimal wear, which helps extend the service life of the sealing cap 40 and the mounting base 30.

[0033] According to some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the sealing cover 40 includes a sealing cover body 41 and a sealing ring 42. When the sealing cover 40 is fixed to the mounting base 30, the sealing cover body 41 covers the maintenance hole 21, and the sealing ring 42 is located between the sealing cover body 41 and the electrical control cover plate 20 to seal the gap between the sealing cover body 41 and the electrical control cover plate 20. The sealing ring 42 is arranged around the maintenance hole 21 in the circumferential direction.

[0034] With the sealing cover 40 fixed to the mounting base 30, the sealing cover body 41 covers the maintenance hole 21, thereby reducing the risk of external moisture, dust, mud, insects, corrosive gases, etc., entering the equipment and maintaining internal cleanliness. It also provides safety protection; the sealing cover 40 prevents accidental contact and injury. In the event of a minor internal explosion or component detachment, the sealing cover 40 acts as a barrier, preventing internal fragments from flying out and injuring people.

[0035] The sealing ring 42 is located between the sealing cover body 41 and the electrical control cover plate 20 to seal the gap between them. The sealing ring 42 is positioned circumferentially around the maintenance hole 21, providing a sealing effect. The sealing ring 42 completely surrounds the maintenance hole 21, geometrically sealing all potential leakage channels between the hole edge and the sealing cover 40, ensuring a seamless seal. The clamping force is transmitted through the sealing cover 40 to the annular sealing ring 42. Because the sealing ring 42 is a continuous closed loop, its elastic deformation evenly distributes and balances the pressure across the entire circumference, preventing excessively high or low local pressure and thus preventing localized leakage. This effectively prevents external moisture, dust, mud, insects, corrosive gases, etc., from entering the equipment, maintaining internal cleanliness.

[0036] According to some embodiments of the present invention, such as Figure 1As shown, a first mounting groove 43 is formed on the side of the sealing cover body 41 facing the electronic control cover plate 20, and a portion of the sealing ring 42 is fitted into the first mounting groove 43; and / or The electronic control cover plate 20 has a second mounting groove on the side facing the sealing cover body 41, and part of the sealing ring 42 is fitted into the second mounting groove.

[0037] In one embodiment of the present invention, a first mounting groove 43 is formed on the side of the sealing cover body 41 facing the electronic control cover plate 20, and a portion of the sealing ring 42 is assembled in the first mounting groove 43.

[0038] Alternatively, as another embodiment of the present invention, the electronically controlled cover plate 20 has a second mounting groove formed on the side facing the sealing cover body 41, and a portion of the sealing ring 42 is fitted into the second mounting groove.

[0039] Alternatively, as another embodiment of the present invention, the first mounting slot 43 and the second mounting slot exist simultaneously.

[0040] You can make reasonable selections and settings based on the actual situation.

[0041] In a specific embodiment of the present invention, the first mounting groove 43 and the second mounting groove coexist. When the sealing cover 40 is placed over the inspection hole, the sealing ring 42 is located between the sealing cover body 41 and the electrical control cover plate 20, with a portion of the sealing ring 42 fitted into the first mounting groove 43 and a portion fitted into the second mounting groove. During reciprocating or rotating motion, the sealing ring 42 in a single groove is prone to circumferential torsion or axial rolling due to friction, leading to seal failure or even tearing. The first mounting groove 43 and the second mounting groove simultaneously restrict the position of the sealing ring 42 from both sides, ensuring that it can only be compressed and deformed, preventing overall torsion, thus greatly improving the stability and lifespan of the dynamic seal.

[0042] The first mounting groove 43 and the second mounting groove can also provide bidirectional positioning. The guiding effect of the double grooves makes the sealing ring 42 automatically centered, avoiding displacement or detachment. For large or vertically installed sealing surfaces, this design eliminates the need for temporary bonding to fix the sealing ring 42, improving assembly efficiency and reliability.

[0043] According to some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the sealing cover 40 also includes a fixing post 44, which is fixedly connected to the sealing cover body 41, and the fixing post 44 is detachably connected to the mounting base 30.

[0044] The fixing post 44 and the sealing cover body 41 are fixedly connected. In some embodiments of the present invention, the fixing post 44 and the sealing cover body 41 can be integrally formed, or the fixing post 44 and the sealing cover body 41 can be fixedly connected by adhesive bonding. However, the present invention is not limited to this, and the fixing post 44 and the sealing cover body 41 can also be fixedly connected in other ways, as long as the fixing post 44 and the sealing cover body 41 are fixedly connected. The fixing post 44 is detachably connected to the mounting base 30, so that the sealing cover 40 is detachably connected to the mounting base 30. Maintenance of the high-voltage busbar can be achieved by removing the sealing cover 40, eliminating the need to disassemble and reassemble the entire electrical control cover 20, thereby greatly improving the maintenance efficiency and convenience of the high-voltage busbar in the electrical control device 100.

[0045] According to some embodiments of the present invention, such as Figure 2 As shown, the outer peripheral wall of the fixing column 44 is formed with external threads to connect with the mounting base 30. This design allows the sealing cover 40 to be installed and removed simply by tightening and loosening the threads. Maintenance can be completed with only one tool removal, eliminating the need to disassemble the entire electrical control cover 20. This greatly improves the maintenance efficiency and convenience of the high-voltage busbar in the electrical control device 100.

[0046] Furthermore, compared to bolted connections, threads effectively prevent automatic loosening by relying on the friction and radial expansion between the threaded pairs. They are also vibration-resistant, reducing the number of parts and the risk of loosening. The sealing cap 40 can be directly screwed into the access port. Its overall shape is cylindrical or conical, without radially protruding flanges or handles. This is highly advantageous for installations in confined spaces, densely packed pipes, or where low wind resistance is required, greatly improving the positional flexibility of the electrical control device 100 and reducing maintenance difficulty.

[0047] Normally, tightening or loosening can be achieved with just an adjustable wrench, pipe wrench, or special wrench, without the need to disassemble or assemble multiple bolts or operate clamps. The threaded structure experiences minimal wear, which helps extend the service life of the sealing cap 40 and the mounting base 30.

[0048] According to some embodiments of the present invention, such as Figure 1 As shown, the mounting base 30 has a mounting hole 31 for mounting the sealing cover 40. The fixing post 44 extends into the mounting hole 31 and is threadedly engaged with the mounting base 30, which can increase the connection area between the sealing cover 40 and the mounting base 30, thereby increasing the connection strength between the sealing cover 40 and the mounting base 30, so that the sealing cover 40 is securely mounted on the mounting base 30, thereby reducing the risk of sealing failure of the maintenance hole 21.

[0049] In some embodiments of the present invention, the assembly hole 31 is a threaded hole so that the fixing post 44 and the mounting base 30 are threadedly engaged. This arrangement allows the sealing cover 40 to be disassembled and assembled by simply tightening and loosening the threads. Maintenance can be completed with only one tool disassembly, eliminating the need to disassemble and assemble the entire electrical control cover 20. This greatly improves the maintenance efficiency and convenience of the high-voltage busbar in the electrical control device 100.

[0050] According to some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the mounting base 30 and the electrical control cover 20 engage with each other to fix the mounting base 30 to the electrical control cover 20. The engagement structure (such as elastic clips, barbs, and screw clips) allows for easy fixing by manual pressing or simple pushing, eliminating the need for screwing, aligning threaded holes, and pre-tightening. This significantly improves the assembly efficiency of the mounting base 30, reduces labor costs, and the engagement features can be directly integrated into the mounting base 30 or the electrical control cover 20 (such as the elastic arms and protrusions inherent in injection-molded parts), eliminating the need for separate procurement, storage, and distribution of small parts such as screws, washers, and spring washers. This saves material costs and avoids the problem of lost or missing parts on-site.

[0051] According to some embodiments of the present invention, such as Figure 2 As shown, the mounting base 30 includes: a mounting base body 32, a limiting flange 33, and an elastic snap-fit ​​arm 34. The mounting base body 32 has an assembly hole 31. The limiting flange 33 is fixed to the end of the mounting base body 32 near the electronic control cover plate 20. The elastic snap-fit ​​arm 34 is fixed to the mounting base body 32 and extends axially along the assembly hole 31. The end of the elastic snap-fit ​​arm 34 away from the mounting base body 32 has a limiting portion 35. The limiting portion 35 and the limiting flange 33 are spaced apart axially along the assembly hole 31 to form a snap-fit ​​space 36 for assembling the electronic control cover plate 20 between the limiting portion 35 and the limiting flange 33.

[0052] The mounting base body 32 has an assembly hole 31 for assembling the fixing post 44. A limiting flange 33 is fixed to the end of the mounting base body 32 near the electrical control cover plate 20. An elastic snap-fit ​​arm 34 is fixed to the mounting base body 32 and extends axially along the assembly hole 31. When installing the mounting base 30, the mounting base 30 extends out of the maintenance hole 21 from the installation space 11. Due to the deformation of the elastic snap-fit ​​arm 34, the elastic snap-fit ​​arm 34 can extend out of the maintenance hole 21. The limiting flange 33 is located within the installation space 11 and extends circumferentially along the maintenance hole 21. Furthermore, the elastic snap-fit ​​arm 34 abuts against the inner wall of the electrical control cover 20. The end of the elastic snap-fit ​​arm 34 facing away from the mounting base body 32 has a limiting part 35, which abuts against the outer wall of the electrical control cover 20. The limiting part 35 and the limiting flange 33 are axially spaced along the assembly hole 31, forming a snap-fit ​​space 36 between the limiting part 35 and the limiting flange 33 for assembling the electrical control cover 20. This enables the snap-fit ​​engagement between the mounting base 30 and the electrical control cover 20. The mounting base 30 can be fixed by manual pressing or simple pushing, eliminating the need for screw tightening, aligning threaded holes, and pre-tightening. This significantly improves the assembly efficiency of the mounting base 30, reduces labor costs, and the snap-fit ​​feature can be directly integrated into the mounting base 30 or the electrical control cover 20 (such as the elastic arm or protrusion inherent in injection-molded parts), eliminating the need for separate procurement, storage, and distribution of small parts such as screws, washers, and spring washers. This saves material costs and avoids the problem of lost or missing parts on-site.

[0053] Furthermore, such as Figure 1 As shown, when the sealing cover 40 is assembled with the mounting base 30, a mis-proof structure 46 can be formed on the side of the sealing cover body 41 away from the mounting base 30, so that the sealing cover 40 can only be removed with a tool corresponding to the mis-proof structure 46, thereby preventing accidental or malicious disassembly and improving the safety and reliability of the electronic control device 100. A clearance groove 45 can be formed on the side of the sealing cover body 41 near the mounting base 30. The clearance groove 45 can be set around the maintenance hole 21 circumferentially, and is used to avoid the limiting part 35, so as to ensure that the sealing cover 40 and the mounting base 30 can be assembled in place.
